Sig Sauer
The SIG SAUER Romeo4T-PRO is a closed-emitter red dot sight built for shooters who demand durability and performance in demanding conditions. Whether you're running a modern MSR platform, a semi-automatic pistol, or a shotgun, this compact sight delivers a clean, fast sight picture for short- to medium-range engagements. It's designed and assembled in the USA for professionals and serious sport shooters who won't compromise on reliability.
At its core is SIG's Quad Ballistic Circle Dot reticle—a proven aiming system that works intuitively for both aimed and rapid shooting. The 1x magnification and 20mm clear aperture keep your full field of view intact, while the red illumination remains visible in bright daylight and low-light scenarios thanks to engineered lens coatings optimized for both conditions. Top-mounted brightness controls let you dial in the perfect intensity across 9 daytime and 3 night-vision settings, and the NV Override function gives you quick access to a preset NV level without cycling through every step.
Durability is built in. The sight ships with two mounting heights so you can dial in your cheek weld to your platform, plus clear flip-back covers, an opaque front cap, and an ARD (Anti-Reflection Device) to eliminate glint. The robust half-inch hex mount locks solid, and the 50000-hour runtime on a single CR2032 battery means you're covered for years of hard use. The MOTAC (Motion Activated) feature helps preserve battery life when the sight sits idle.

It's designed for modern semi-automatic pistols, MSR (modern sporting rifle) platforms, and shotguns. Two mounting heights are included so you can match the sight to your platform and cheek weld.
The sight runs for 50000 hours on a single CR2032 battery. That's roughly 5.7 years of continuous use, and the MOTAC feature helps extend battery life by powering down the reticle when motion isn't detected.
You get the sight, two mounting heights, clear flip-back lens covers, an opaque front cover, an ARD (Anti-Reflection Device) to reduce glint, and the CR2032 battery.
Yes. The engineered lens coatings are optimized for both bright daylight and low-light performance, and you can access 3 dedicated night-vision settings. The NV Override function lets you quickly jump to your preferred NV brightness without cycling through daytime levels.
